Blackened Rolling Block is a casting part of filter assembly machine, placed next to the rolling drum, functioning together to roll the tipping paper and connect the filter and the cigarette.

Advantages Of Blackening

Blackening can be done in large batches (ideal for small parts).

There is no significant dimensional impact (the blacking process creates a layer about a micrometre thick).

It is far cheaper than similar corrosion protection systems, such as paint and electroplating.

Shipping Terms

Preferred: EXW, FOB, CIF, CFR

It had always been first priority to provide quotation with EXW terms applied price. Still for final shipment the other 3 sets of shipping terms are most recommended. We would like to have the export clearance process done by ourselves since we know China’s customs more than clients. Also the tax rebate procedure can be simplified if we clear the custom ourselves.

For any other set of shipping terms especially in which export clearance is not our obligation to deal with, please contact with us for further detail negotiation, so as to avoid any discordance.

Hot Blackening

Hot blackening involves dipping the part into various tanks. The work piece is usually "dipped" by automated part carriers for transportation between tanks. These tanks contain, in order, alkaline cleaner, water, caustic soda at 140.5 °C (284.9 °F) (the blackening compound), and finally the sealant, which is usually oil. The caustic soda bonds chemically to the surface of the metal, creating a porous base layer on the part. Oil is then applied to the heated part, which seals it by "sinking" into the applied porous layer. It is the oil that prevents the corrosion of the workpiece.
